Communication: formula sheet

Full chapter guide

Key formulas

Core idea of communication: Communication = Sender → Message → Receiver → Feedback; Understanding by the receiver and feedback make it complete. Sending alone is not enough.
Key features to remember: Two or more parties + common understanding + two-way + continuous + purposeful + verbal or non-verbal; Use this as a checklist when writing a features answer.
Main objectives: Inform, persuade, instruct, motivate, build relationships, get feedback, support decisions; Give each with a short business example.
Sequence of the process: Sender (idea) → Encoding → Message → Channel → Receiver → Decoding → Feedback; Learn the order. Some books add 'ideation' before encoding and 'noise' across all stages.
Encoding: Encoding = converting an idea into words, symbols or signs; Done by the sender.
Decoding: Decoding = interpreting the message to get its meaning; Done by the receiver. Do not swap it with encoding.
Feedback: Feedback = receiver's response to the sender; It completes the cycle and checks understanding.
Noise: Noise = any disturbance that distorts the message at any stage; It can be physical, language-related, psychological or technical.
Classification by expression: Verbal (oral + written) | Non-verbal; Verbal uses words; non-verbal uses body language, tone, signs and silence.
Classification by formality: Formal (official channels) | Informal (grapevine); Formal follows the chain of command; informal does not.
Classification by direction: Downward | Upward | Horizontal | Diagonal; Downward is top to bottom; upward is bottom to top; horizontal is same level; diagonal is different level and different department.
Grapevine types: Single strand | Gossip | Probability | Cluster; Cluster is the most common pattern in practice.
The 7 Cs: Clarity, Conciseness, Correctness, Completeness, Courtesy, Consideration, Concreteness; Learn them in this order. Be ready to define each in one line and give an example.
Conciseness test: Message = all needed facts − unnecessary words; Cut repetition and wordy phrases. Never cut a fact the receiver needs.
You-attitude: Consideration = receiver's needs first ("you" view over "I" view); Write about what the receiver gains or must do.
Five groups of barriers: Physical + Semantic + Psychological + Organisational + Cultural; Some books add personal or technological barriers. If the question names five, use these five.
Core test for each type: Physical = environment or medium; Semantic = words; Psychological = mind; Organisational = structure; Cultural = background; Use this one-line test to classify any example.
Answer pattern: Type → Meaning → Example → Remedy; Follow this order for every written answer so no marks are missed.
Mode versus medium: Mode = form of message (oral / written / electronic); Medium = tool used (call, letter, email); Do not use the two terms as if they mean the same thing.
Oral communication, key points: Fast + instant feedback + personal touch, but no record + risk of forgetting; Best for urgent, simple or sensitive-to-tone matters.
Written communication, key points: Permanent record + legal proof + clarity, but slow + delayed feedback + costly; Best for formal, detailed or legally important matters.
Electronic communication, key points: Speed + low cost + wide reach + attachments, but technology dependence + security risk; Best for quick, far-reaching messages that still need a stored record.
Medium selection factors: Urgency, need for record, complexity, confidentiality, audience size, cost; Use these six factors to justify your choice in any situation question.

Quick revision

Communication is a two-way exchange of information, ideas or feelings that ends only when the message is understood.
Basic process elements: sender, encoding, message, channel, receiver, decoding and feedback.
Feedback completes the cycle and tells the sender if the message was understood.
Noise is anything that distorts the message at any stage of the process.
Formal communication follows the official structure; informal communication flows outside it.
Communication can be verbal (oral or written) or non-verbal, such as gestures and tone.
The 7 Cs: clarity, conciseness, concreteness, correctness, courtesy, consideration and completeness.
Check each message against the 7 Cs before sending it.
Barriers can be semantic, physical, psychological or organisational, and each needs a different remedy.
Choose the medium by urgency, need for a record, cost, confidentiality and audience.
In written answers, give definition, points and a short example.
Use headings or numbered points so the examiner can see each idea quickly.

Common mistakes

Defining communication only as sending a message Fix: Always include understanding by the receiver and feedback in your definition.
Mixing up features, objectives and importance Fix: Features describe what communication is. Objectives describe what you want to achieve. Importance describes the benefit to business. Keep three separate lists.
Swapping encoding and decoding. Fix: Remember: the sender encodes, the receiver decodes. En- is for sending out the idea.
Treating the message and the channel as the same thing. Fix: The message is the content. The channel is the route, like email, phone or letter.
Treating written communication as non-verbal because no one speaks. Fix: Verbal means words, spoken or written. Non-verbal means no words, such as gestures and tone.
Calling all informal communication gossip. Fix: Informal communication also carries useful, accurate news. Note that it is unofficial and unverified, not always false.
Confusing clarity with concreteness Fix: Clarity is about simple, unambiguous expression. Concreteness is about specific facts and figures. Give each a different example.
Treating conciseness as making the message short at any cost Fix: Remove only needless words. Keep every fact the receiver needs. That is also completeness.
Calling jargon a cultural barrier Fix: If the problem is difficult words or unclear meaning, choose semantic. Choose cultural only when customs, values or norms differ.
Treating psychological and semantic barriers as the same Fix: Semantic is about the words used. Psychological is about the mental state of the person. Write this difference in one line.

Exam tips

Always write a definition first, even if the question asks only for features or importance.
Use bold headings for points so the examiner can scan your answer quickly.
Keep features, objectives and importance in separate lists, and give a short business example.
In the written paper, match the number of points to the marks rather than writing long paragraphs.
Link a point to company situations, such as notices to shareholders, to show application.
Learn the order of elements as one chain and write it first in any long answer.
In written answers, define each element in a line and add a short Indian business example to score better.
Draw a neat diagram with arrows and a feedback loop if space allows. Label noise.
